Confusing range notation

[rdhelli]

@ Term2/Lesson11/Concept8 There should be a better notation for the position ranges, as it was confusing to read "4 - 6" (as in 4 minus 6). My suggestion is this instead: "Accounting for a position precision of +/- 1.0 meters, this places our car at an initial position in the range [4..6] (5 +/- 1), [9..11] (10 +/- 1), or [19..21] (20 +/- 1)."

Valid point. I'm actually changing it to [4, 6] to follow interval notation, but achieves the same clarifications as you've noted. Thank you!
